Specialists from the Research Institute of Mechanics of Moscow State University named after M.V. Lomonosov have created a prototype of a pump-dispenser that can be controlled remotely using a magnetic field.
The basis of the new device is a magnetic fluid with a magnetizable body inside. With the help of an external uniform magnetic field, which is concentrated by this body, it is possible to precisely control the operation of the pump.
According to Daria Pelevina, leading researcher at the Laboratory of Physical and Chemical Hydrodynamics, this system allows precise dosing of liquid and changing the flow rate without touching the device itself.
The use of a uniform magnetic field also makes it possible to reduce the size of the pump, since the operation of the device does not depend on changes in the strength of the magnetic field at different points.
